Hey guys, I am in some serious need of help. My truck has been in the shop for almost 3 weeks now. It failed emission due to a P0138 code indicating a high voltage with my after cat sensors. I need some help to fix it. We've have automotive electrical specialist look at it and no one's got a clue. We've replaced computers, the sensors, wires. We're out of ideas, I am welcome to all ideas and craziness (aside from buying a new truck).

 

Aww crap man, I hate electrical problems... them damn gremlins.

I can't really help I wanna wish you good luck... I'm assuming you've already tried replacing the sensors.

 

P0138 1/2 O2 sensor shorted to voltage.

What happens when they disconnect the O2 sensor? Is this an auto or manual transmission? The wiring is different m/t vs a/t.

 

Automatic, I'll ask, I can't do electrical stuff. But I'll get back to you tomorrow with an answer on that
